IMEI field goes blank Galaxy S GT-i9003
My galaxy s gt-i9003 's Imei has been lost while phone was kept idle. IMEI field shows Unknown in "settings" and do not show anything on "*#06#".
I rooted it with superoneclick and flashed DDMF1 ROM to it (expecting it would resolve the issue) but it did not help.
Also now, I'm not able to root it though the phone is working fine except lost imei.
Also tried some writeIMEI tool but no help.
Can you please tell me what could be done to resolve this.
